Indicator recalculation

[DGDario]

Hi,
I've developed an indicator that has a parameter configurable.
The only way to recalculate the past when the parameter's configuration changes is saving the data at every interval?

Hi,
If you are using Simplified API you need to call reload() method of your Api object on a parameter change.

Code: Select all

private Api api;

@Override
public void initialize(String alias, InstrumentInfo info, Api api, InitialState initialState) {
    this.api = api;

Code: Select all

//on settings updated
    api.reload();

If you are using Core API you need to call the invalidate() method of the InvalidateInterface object associated with your indicator.

I've tryed with the api.reload() but it doesn't recalculate the indicator for the past data

Does you module implement HistoricalDataListener or HistoricalModeListener?

Implementing HistoricalDataListener works! thank you Andrey
